# ``Swift/Character``

## Topics

### Creating a Character

In addition to creating a character from a single-character string literal, you can
also convert a unicode scalar value or single-character string.

- ``Swift/Character/init(_:)-6o1aq``

### Writing to a Text Stream

- ``Swift/Character/write(to:)``

### Comparing Characters

- ``Swift/Character/==(_:_:)``
- ``Swift/Character/!=(_:_:)``
- ``Swift/Character/<=(_:_:)``
- ``Swift/Character/<=(_:_:)-1ihf``
- ``Swift/Character/>(_:_:)-24u5o``
- ``Swift/Character/>=(_:_:)-8lyhz``
